Prepare for GTA5 Updates - Video

Here is the how-to video.

Note: in this video we only backup 4 files. This is based on previous updates, so if in doubt backup all your modified files. After many updates, we've found only updating GTA5.exe is necessary.

You may also ask why we backed up the file update.rpf since it will not be overwritten or impacted by the update. The reason for this is that at one point OpenIV will ask to overwrite this file with the updated game version. 

If you allow this, without a backup, you will essentially lose your dlclist.xml, gameconfig.xml, and any other modified files inside update.rpf. In other words, none of your addons (vehicles, maps, peds) listed in your previous dlclist.xml will load because they have been replaced with a vanilla file. They will still be installed, just overlooked.
